3M 7000044800 Wetordry Polishing Paper 281Q 3.0 Micron

Product Description

The 3M 7000044800 is a Wetordry Polishing Paper sheet in the 281Q series, designed for fine finishing and polishing of contoured surfaces. It features aluminum oxide abrasive particles bonded to a flexible nonwoven backing that conforms to curved and irregular profiles. At a 3.0 micron grade, this sheet delivers consistent micro-finish results on softer materials including plastics, aluminum, brass, and copper. It is suitable for use wet or dry, giving technicians flexibility based on the application and surface requirements. Finishing trades, toolmakers, and precision fabricators typically use this product in final-stage surface prep and polishing work.

This polishing paper is used in applications requiring fine surface finishing on non-ferrous metals and plastics. Common scenarios include optical component finishing, precision part deburring, mold and die polishing, and surface conditioning on aluminum or copper fittings. The flexible nonwoven backing allows the sheet to conform to contoured geometry without cutting through edges or high spots. The 281Q series is available in 1.0, 2.0, 3.0, and 9.0 micron grades to match the progression of finishing steps required for a given surface finish specification.

Installation Notes

This abrasive sheet is applied by hand or wrapped around a sanding block and requires no mechanical installation. When used wet, ensure the work surface and any adjacent components are compatible with water or the chosen lubricant. Wear appropriate eye protection and gloves when handling abrasives, particularly on metal workpieces. Inspect the sheet for loading or tearing before each use and replace when abrasive performance degrades.
